FIG. 1A-FIG. 1B depicts a perspective view of a front of an electronic reading device 110 and a back of an electronic reading device 110 according to one or more aspects of the disclosed subject matter.

The electronic reading device 110 (also referred to as e-reader 110, electronic reader 110, the device 110, etc.), is an electronic personal display that is used for reading electronic books (eBooks), electronic magazines, and other digital content. For example, digital content of an eBook is displayed as alphanumeric characters and/or graphic images on a display of an e-reader such that a user may read the digital content much in the same way as reading the analog content of a printed page in a paper-based book. An e-reader provides a convenient format to store, transport, and view a large collection of digital content that would otherwise potentially take up a large volume of space in traditional paper format.

In some instances, e-readers are purpose built devices designed especially to perform especially well at displaying readable content. For example, a purpose built e-reader may include a display that reduces glare, performs well in high light conditions, and/or mimics the look of text on actual paper. While such purpose built e-readers may excel at displaying content for a user to read, they may also perform other functions, such as displaying images, emitting audio, recording audio, and web surfing, among others.

There also exists numerous kinds of consumer devices that can receive services and resources from a network service. Such devices can operate applications or provide other functionality that links the device to a particular account of a specific service. For example, e-reader devices typically link to an online bookstore, and media playback devices often include applications which enable the user to access an online media library. In this context, the user accounts can enable the user to receive the full benefit and functionality of the device.

The electronic reading device 110 can enhance electronic reading activity, according to an embodiment. The electronic reading device 110 can include an electronic display device and a network service as further described herein. The network service may include multiple servers and other computing resources that provide various services in connection with one or more applications that are installed on the e-reader device. By way of example, in one implementation, the network service can provide e-book services which communicate with the e-reader device. The e-book services provided through network service can, for example, include services in which e-books are sold, shared, downloaded and/or stored. More generally, the network service can provide various other content services, including content rendering services (e.g., streaming media) or other network-application environments or services.

The e-reader device 110 can correspond to any electronic personal display device on which applications and application resources (e.g., e-books, media files, documents) can be rendered and consumed. For example, the e-reader device 110 can correspond to a tablet or a telephony/messaging device (e.g., smart phone). In one implementation, for example, e-reader device 110 can run an e-reader application that links the device to the network service and enables e-books provided through the service to be viewed and consumed. In another implementation, the e-reader device 110 can run a media playback or streaming application which receives files or streaming data from the network service. By way of example, the e-reader device 110 can be equipped with hardware and software to optimize certain application activities, such as rendering of electronic content (e.g., e-books). For example, the e-reader device 110 can have a tablet like form factor, although variations are possible. In some cases, the e-reader device 110 can also have an E-ink display.

In additional detail, the network service can include a device interface, a resource store and a user account store. The user account store can associate the e-reader device 110 with a user and with an account. The account can also be associated with one or more application resources (e.g., e-books), which can be stored in the resource store. As described further, the user account store can retain metadata for individual accounts to identify resources that have been purchased or made available for consumption for a given account. The e-reader device 110 may be associated with the user account, and multiple devices may be associated with the same account. The e-reader device 110 can store resources (e.g., e-books) that are purchased or otherwise made available to the user of the e-reader device 110, as well as to archive e-books and other digital content items that have been purchased for the user account, but are not stored on the particular computing device.

FIG. 2 depicts a system for operating a computing device (e.g., the electronic reading device 110) to enhance electronic reading activity according to one or more aspects of the disclosed subject matter. The e-reader device 110 includes a housing 206 that includes a display screen 208 on which text content from selected e-books can be rendered. The e-reader device 110 also includes a separate or independent illumination component 218 for the display screen 208. In some examples provided herein, the illumination component 218 is provided as a front light, which directs light onto the display surface 208 from a housing bezel or thickness. It should be appreciated that the illumination 218 is not limited to the sides of the screen. For example, the illumination 218 can be positioned at the bottom of the screen, as may be seen for the adjustable RBGW front light as further described in 475277US, which is herein incorporated by reference in its entirety.

The display area 208 can be configured as a touch sensitive component of a display assembly on which input features are provided or are otherwise enabled. By way of example, the input features can include soft buttons or hidden touch regions where the user can transition pages from an e-book, looking words up (using a dictionary function).

According to some examples, the illumination component 218 independently illuminates the display screen 208 in order to create a visual effect. The visual effect can correspond to, for example, illuminating an otherwise non-illuminated screen (such as provided by electronic paper type displays). The illumination can further be provided with characteristics, such as luminosity, color, and and/or other lighting effects.

The e-reader device 110 can include illumination control logic 212 that controls one or more illumination aspects of the illumination component 218. The illumination component 218 may be a front light. As described with examples, the control logic 212 can control one or more of the color, the luminosity, lighting affect (e.g., blinking or modulation), or other illumination characteristic. Furthermore, in some variations, the control logic 212 controls the illumination component 218 in a manner that is responsive to triggers. As described with various examples, the illumination component 218 can be responsive to software-implemented triggers, sensor implemented triggers, and/or hardware component related triggers. Additionally, the illumination component 218 can be responsive to settings and/or input provided by a user through interaction with the-reader device 110. As described with examples, the control logic 212 controls the lighting aspects of the illumination component 218 while the display screen 208 is used to render content, such as pages of an e-book. In this way, the illumination component 218 can generate ambience, illumination environment, and/or status information independently of content displayed on the display screen 208.

In one implementation, the illumination component 218 is provided in the form of light emitting diodes (LEDs) or other discrete light sources that are disposed in a housing 206 of the e-reader device 110. The front light 218 can be programmatically controllable to modulate in color, luminosity and/or affect. The orientation of the illumination component 218 directs light onto the display screen 208 independent of content rendered through the display screen. As shown with examples of FIG. 7B and FIG. 7C, the light sources that comprise the illumination component 218 can be disposed in a bezel of the housing 206 so as to cast light on to the display screen 208.

The electronic reading device can include a front light, and more specifically an adjustable RGBW front light. Various hardware components, as further described herein, may contribute to the operation of the electronic reading device. For example, the various hardware components may receive instructions from the illumination control logic 212. Additionally, the electronic reading device can have a range of dimensions to incorporate the various hardware components. However, the depth of the electronic reading device can be less than seven millimeters. More specifically, the depth of the electronic reading device can be 6.99 millimeters due at least in part to the structural design as further described herein.

FIG. 3A depicts a perspective view of a front 310 of the electronic reading device 110 according to one or more aspects of the disclosed subject matter.

The front 310 can also include an ambient light sensor opening 315 and a tri-color status LED 320, as further described herein.

FIG. 3B depicts a perspective view of a back 330 of the electronic reading device 110 according to one or more aspects of the disclosed subject matter. The back of the electronic reading device 110 can include a power/sleep button 325, as further described herein.

FIG. 4A is a close up view of an upper right corner of a front 405 of an electronic reading device 110 according to one or more aspects of the disclosed subject matter. The front 405 can include a display 420 (e.g., display 208 in FIG. 2). The upper right corner of the front 405 of the electronic reading device 110 can include various components including an ambient light sensor opening 410 and a tricolor status LED 415. The ambient light sensor opening 410 can provide an entry point for ambient light to reach an ambient light sensor. The tricolor status LED 415 can be a substantially square shape with rounded corners. Additionally, the tricolor status LED 415 can be a predetermined color. The tricolor status LED 415 can indicate various interactions with the electronic reading device 110.

FIG. 4B is a close up view of an upper left corner of a back of an electronic reading device according to one or more aspects of the disclosed subject matter. The upper left corner of the back 430 of the device 110 can include a power/sleep button 425. The power/sleep button 425 can be recessed and/or a predetermined color. The tricolor status LED 415 of FIG. 4A and the power/sleep button 425 can be the same predetermined color. Additionally, the power/sleep button 425 is a substantially square shape with rounded corners. Further, the tricolor status LED 415 can be in line along the same axis as the power/sleep button 425. The similar shape, color, and position of the tricolor status LED 415 and the power/sleep button 425 can provide various aesthetic and functional advantages. The advantages can include creating an intuitive user experience, as well as providing confidence in the user's interaction with the power/sleep button 425, as an interaction with the power/sleep button 425 causes an activation of the similarly shaped, colored, and positioned tricolor status LED 415.

The back 430 of the electronic reading device 110 can include a back cover 425. The back cover 425 can include predetermined patterns for various stylistic and aesthetic purposes, as well as for providing grip to assist in holding the electronic reading device 110. The patterns may be laser cut, for example, such that at least a portion of the pattern includes a predetermined depth.

FIG. 5A depicts a perspective view of an upper right corner of a front 510 of an electronic reading device 110 according to one or more aspects of the disclosed subject matter. The upper right corner of the front 510 of the electronic reading device 110 can include a plurality of micro laser through holes 505. The plurality of micro laser through holes 505 can be configured to allow a predetermined light (e.g., an LED) to be seen in response to one or more interactions with the electronic reading device 110. Additionally, the plurality of micro laser through holes 505 can be a predetermined number of micro laser through holes 505 in a predetermined positional configuration. The micro laser through holes 505 can be configured to increase consistency of a non-touch area of the front 510 of the device 110, such that the front 510 of the device 110 maintains a predetermined level of visual consistency in the non-touch areas of the front 510 of the device 110. The non-touch sensitive portion of the front 510 can outline the display of the device 110. Further, the micro laser through holes 505 can provide an area through which light is visible in response to one or more interactions with the electronic reading device 110.

The plurality of micro laser through holes 505 can correspond to a predetermined number of micro laser through holes such that the predetermined number of micro laser through holes optimizes the visibility of the light displayed through the micro laser through holes 505 with the predetermined level of visual consistency of the non-touch sensitive portion of the front 510 of the electronic reading device 110. In other words, the light can be visible while the number of micro laser through holes remains low enough to maintain the predetermined level of visual consistency.

Additionally, the plurality of micro laser through holes 505 can include a predetermined positional configuration optimizing the visibility of the light displayed through the micro laser through holes 505 with the predetermined level of visual consistency of the non-touch sensitive portion of the front 510 of the electronic reading device 110. Similarly, the area through which light is visible in response to the one or more predetermined interactions with the electronic reading device 110 can occupy a predetermined amount of space of the non-touch sensitive portion of the electronic reading device 110. The predetermined amount of space of that the micro laser through holes 505 occupy on the non-touch sensitive portion of the electronic reading device 110 can be a square with predetermined dimensions based on the size of the display, for example.

The light displayed through the micro laser through holes 505 can correspond to a predetermined color of light based on the one or more interactions with the electronic reading device. For example, the color of the light can change based on a type of notification (e.g., low battery, download complete, and the like). In other words, any notification of the device can be associated with a color and activated when that notification occurs, for example.

FIG. 5B depicts a perspective view of an upper left corner of a back of the electronic reading device 110 according to one or more aspects of the disclosed subject matter. The back of the electronic reading device 110 can include a power/sleep button 515 (e.g., power/sleep button 425 in FIG. 4B).

FIG. 6 depicts an electronic reading device 110 including a reverse draft structure according to one or more aspects of the disclosed subject matter. The reverse draft structure corresponds to a back 615 of the electronic reading device 110 being wider than a front 610 of the electronic reading device 110. More specifically, the reverse draft can be at an angle of seven degrees relative to vertical, the vertical being an axis perpendicular to the front 610 of the device 110. In other words, the back 615 of the device is seven degrees wider than the front 610 of the device 110. The reverse draft allows accessories to attach to the device 110 while remaining flush with the front 610 of the device 110. For example, a protective case for the electronic reading device 110 may be attached such that a section of the protective case that secures the case to the device does not use the face of the device to secure the protective case. To the contrary, the protective case can be secured to the electronic reading device 110 via the reverse draft. Because the back 615 of the device 110 is wider than the front 610 of the device 110, the protective case can be sufficiently secured to the electronic reading device 110 while being flush with the front 610 of the electronic reading device 110 (i.e., the section of the protective case that attaches to the electronic reading device 110 does not exceed a predetermined height above the front 610 of the electronic reading device 110).
